If you are getting the 21 PSI boost from the Megasquirt site then the sensor they specify is actually 2.5 bar absolute so (2.5 * (14.7)) - 14.7 = 22 PSI of boost, but that would be pushing the limits of the sensor! If you are talking true 2 bar then the boost is only 14.7 PSI.
I agree that the sensor can probably read slightly higher than its operating range but it wouldn't be desirable to operate it there. Technically you could probably also run a lot higher pressure before permanently damaging the sensor diaphragm but this would be useless as you wouldn't be getting a useful voltage reading anyway.
Yes, the longer pipe wouldn't affect the response much as you said. The total response of the engine is relatively slow in comparison to the speed that the calculations are performed in software.
